A day after San Francisco’s mayor announced the departure of the city’s beleaguered police chief, the department’s new leader said Friday his top priority is instituting sweeping changes to the scandal-plagued organization.

“Reforms, reforms, reforms,” interim SFPD Chief Toney Chaplin told reporters when asked where his focus would lay. “The department has to move forward and that’s what I’m here to do. To steer this ship in a direction it was already headed in.”

In an unexpected announcement Thursday afternoon, Mayor Ed Lee said at his request Greg Suhr had resigned as chief after the two met following an officer-involved shooting in which an unarmed black woman in a stolen car was killed.

Lee had previously expressed confidence in Suhr, praising the chief for understanding the need for reform, even as public calls had mounted for his ouster. But the mayor said progress has been too slow.
